【摘要】 本文在论述了钢纤维对混凝土及钢筋混凝土的有限增强作用后,利用一个不掺钢纤维的和两个在节点区、柱端及梁端掺有钢纤维的框架顶层边节点足尺试件的对比试验,从抗震角度探索了此类节点区掺加钢纤维后的有利及不利效果,对钢纤维在抗震钢筋混凝土框架各类节点区的应用前景作了全面估计。更多还原

【Abstract】 This paper first discusses the limited effect of steel fibre reinforcement on plain concrete and reinforced concrete. Then, making a comparison among the test results of three full-scale top corner joint assemblies of frame, in which only two of them are added with steel fibres in joint zone. The advantageous and disadvantageous influence in anti-seismic aspect is investigated after adding steel fibres in the joint zone. Finally, this paper gives an overall comment on the application future of using the steel fibres in every kinds of joint of anti-seismic reinforced concrete frame.更多还原
